Not working with 'Flat' theme

Have you inserted a fancy spoiler shortcode in this post?

Yes, sorry if you saw the post using another spoiler plugin, i was just testing if this issue is related to the theme, I have reverted it back to the Fancy Spoiler one

Could i have admin access to your WordPress dashboard to investigate the issue further? Send me credentials to kouratoras[at]gmail[dot]com.

Fixed, it was an old plugin related to autolinking that was making this issue

Happy to hear you solved this!

If you’re satisfied with my plugin, a review would be really appreciated!

Thank you!
